Add the ability to import and wrap external surfaces from external toolkits such as Qt and GTK.
Wayland surfaces and windows are more intrinsically tied to the client library than other windowing systems, so it is necessary to provide a way to initialize SDL with an existing wl_display object, which needs to be set prior to video system initialization, or export the internal SDL wl_display object for use by external applications or toolkits. For this, the global property SDL_PROPERTY_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER is used.
A Wayland example was added to testnative, and a basic example of Qt 6 interoperation is provided in the Wayland readme to demonstrate the use of external windows with both SDL owning the wl_display, and an external toolkit owning it.
Windows doesn't inform applications if the window is in the docked/tiled state, so let windows manage the window size when restoring from a fixed-size state, unless the application explicitly requested a new size/position.
Fixes the video_getSetWindowState test.
WM_WINDOWPOSCHANGING needs to return 0 when a resize was initiated programmatically
Checking the SWP_NOMOVE and SWP_NOSIZE flags in the WINDOWPOS struct when handling WM_WINDOWPOSCHANGED to avoid sending redundant resize and move events is unreliable, as they can be set even when the window has moved or changed size, such as when leaving fullscreen, or programmatically resizing a window without STYLE_RESIZABLE set.
Fixes the video_getSetWindowSize and video_setWindowCenteredOnDisplay tests.
Applications might override WM_WINDOWPOSCHANGING which would prevent us from getting the correct window state.
This also fixes cases where the window doesn't get WM_SHOWWINDOW, as described in Raymond Chen's blog post:

If testautomation is running with only a specific audio driver enabled, we shouldn't try to open other ones, as they might fail.

(cherry picked from commit 4c11307a4e75fbfde0d8ace6b19d612d2973bf0b)
Allow for the creation of SDL windows with a roleless surface that applications can use for their own purposes, such as with a windowing protocol other than XDG toplevel.
The property `wayland.surface_role_custom` will create a window with a surface that SDL can render to and handles input for, but is not associated with a toplevel window, so applications can use it for their own, custom purposes (e.g. wlr_layer_shell).
A test/minimal example is included in tests/testwaylandcustom.c
A Wayland registry object can only have one listener attached at a time, so an application attempting to use the backend SDL registry object for its own purposes will just result in an error. Remove this property, as it is of no use to applications and will only result in errors.
If an application needs the registry, it needs to get the wl_display object via `SDL.window.wayland.display` and use wl_display_get_registry() to create a new registry object that it can attach its own listeners to.
If the xdg_wm_base protocol isn't present, the window won't be assigned a valid surface type at creation time, which makes these checks redundant.
The libdecor path was already cleaned up in this manner some time ago.
When a test has been disabled because it's known not to work reliably
or it's a test for unimplemented functionality, we probably don't want
to encourage developers and testers to run it and report its failures
as a bug.

It would be easy to assume that all APIs that reference
SDL_JOYSTICK_AXIS_MAX work the same way, but they do not: triggers
generally use the full signed 16-bit range in the lower-level joystick
API, but are normalized to be non-negative by the higher-level gamepad
API.
We also never said explicitly which direction is positive here.
Experimentally, it's right (X), down (Y), and pressed (triggers).
